REPAIR KIT.

Application filed 0ctober 25,i1924. Serial No. 745,846.

To all whom it may concern-3 Be it known that I, RICHARD citizen of-the United States of America, r'e-' siding at Birmingham, in the county of Jefiierson and State of'Ala-bama, have in-.

vented certain new and useful Improvements in Repair Kits, of which the following is a specification.

My invention relates to a tire repair kit comprising a container adapted to recelve.

material for repairing flexible rubber goods, such as pneumatic tubes, rubberbottles, etc., and having incorporated as an end closure of the outfit a metalliecap having a deep marginal flange which is serrated or roughened to provide an effective scraper for cleaning the rubber surface preparatory to applying the adhesive.

I-Ieretofore the scraper elements have been applied in various ways to repair kits of the character in question, such as providing extra serrated bands surrounding the kit or puncturing the end closures to afiord a roughened surface end for scraping the rubher. The former practice is objectionable in that it calls for an added element to be separately applied and that it detracts from the appearance of the kit and the kit cannot be grasped most conveniently and effectively to perform the scraping operation.

The objection to the punctured end of the kit is that this admits air to deteriorate the patch elements and permit access of dirt and oil to injure them when carried in the tool box while in ordinary use. Moreover, such kits are required to be held practically vertical in scraping and do not provide the most convenient grip for work.

The object of my present invention is to simplify and perfect the scraper detail of a repair kit to the end that a scraper element shall be incorporated preferably as part of one of the standard elements of the kit at a minimum expense and that the scraper shall be disposed in position for the kit to be grasped most conveniently and operated most effectively. To these ends I provide either end closure desired of the kit with a wide outer marginal scraper flange spaced from an indented center adapted to fit snugly into an end of the kit to give practically an air tight closure while the scraper flange is held rigid on the end of the kit.

A further distinctive feature of my invention is that the end closure is so designed that the scraper flange flares at an acute W. Fox, at

angle to the long axis of the 'kit so that the latter can be grasped in the hand in the normal way andthe roughened flange presented in substantial parallelism to the plane in which the, rubber surfaceuwill normally lie while being scraped.

My invention further comprises the novel details of construction and arrangements of parts, which are hereinafter more particularly described and claimed, reference being had to the accompanying drawings which illustrate my invention in its preferred embodiments. Y

In'the drawings :c

Fig. 1 is a partial side elevation and a partial vertical sectional view taken through a repair kit with the scraper element incorporated as a part of the screw cap or top closure.

Fig. 2 is a sectional View; of the kit with the scraper element incorporated as a part of its bottom closure.

Fig. 3 is a view showing the manner in which the kit is grasped during the scraping operation.

Similar reference numerals refer to similar parts throughout the drawings.

In the embodiment of my invention illustrated, I show a kit which is conveniently illustrated in the form of a tubular container 1, but obviously the kit may be of any desired shape in cross section and made up of any desired material. The tube in Fig. 1 is shown with a permanently attached bottom closure 2 at one end and it is provided at its top end with a screw cap comprising a central depressed unperforated body por tion 3 adapted to fit snugly into the end of the tube to close it and carrying at its outer end a bent back portion forming an outturned anarginal flange 4 which flares outwardly from the outer end of said body portion 3 and about its free edge is a cylindrical portion 5 threaded to screw onto the threaded end 6 of the container. Threads may be provided on any desired part of the cap which will enable it to be screwed into or onto the tube and constitute a removable tight closure. The flaringflange 4 is punctured from its inner side outwardly before the cap is formed so as to present roughened scraper points 7 of any suitable character which will be adapted for scraping and cleaning the rubber preparatory to patching.

In Fig. 2 I show the kit provided with the Ordinary screw top 8 and having permanently attached on its bottom a scraper closure comprising an indented body portion 9 corresponding to 4 in Fig. 1, and carrying the flaring scraper flange 1O corresponding to 5. The free edge of the flange 10 is crimped in so as to secure the bottom closure to the lower end of the tube with an air tight fit between the body portion 9 and the flange 10. closure 'at the bottom carrying the scraper element. 7

In Fig. 3 I show the manner of use of the scraper element which applies equally to the top or bottom closure. Here the kit tube is grasped in the hand, the slightly inclined scraper flange is laid flat to the rubber to be scraped, and the motion is a free and easy back and forth swing of the arm with the hand held in normal position for applying with greatest ease a heavy downward pressure on the work.

Though I have described with great particularity the details of the embodiment of This will give an air tight the invention herein shown, it is not be construed that I am limited thereto, as changes in arrangement and substitution of equivalents may be made by those skilled in the art without departing from the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a repair kit of the character described, an end closure for a tubular container, Which comprises a body portion adapted to engage and seal an end of the container and a wide external flange over-- lapping the container and perforated to present a roughened external surface, for the purposes described.

2. A kit of the character described in claim 1, in which said roughened flange is disposed with an outward flare at an obtuse angle to the outside of the container.

In testimony whereof I aifix my signature.

RICHARD W. FOX.
